Sunflex SF75h HSW

Timber moveable wall system.

The SF75h Timber horizontal moveable wall system is manufactured using laminated engineered timber sections which increase strength and reduces the risk of twisting or warping, it also enables the minimal sightlines. Panels when closed form a solid union ensuring the very best in security, reliability, thermal efficiency.

All timber is sourced from sustainable forests: the standard timbers are Meranti (hardwood) and Nordic pine (knot free-softwood), while other timbers such as American White Oak are available by special order. The natural beauty of the wood is enhanced by Sunflex’s finishing techniques, resulting in the finished product being comparable to that of high quality furniture.

The SF75h HSW Timber can easily be integrated and will enhance any project, presenting unlimited space organising opportunities. The system is very suitable for commercial applications; from an office or a bank to a school, car showroom or a shopping mall.

Glass Options

As standard all of our products will be fitted with glazing that exceeds Building Regulations Document N and L which govern safety and thermal efficiency. Over our standard glass there are many options for you to choose from including:

Dimensions

Manufacturer recommend panel widths do not exceed 1200mm and a maximum height of up to 3000mm. Heights greater than this can be achieved; please contact our technical department for advice.

Profile

The Sunflex SF75h is manufactured from triple-laminated solid timber sections. These sections have been stabilised at stress points and bonded back together with opposing grains, which creates added strength whilst preventing warping and twisting.

Track options

The top suspended track and rail can be concealed within the ceiling and is therefore entirely without the need of a bottom track, with only floor press stud sockets to accommodate the shootbolt locking rods, leaving an uninterrupted floor surface, bottom track option available if required.

Security

The standard locking system offers a very high level of security, with a quick, smooth and easy operation. Each panel incorporates a bottom shootbolt mechanism which is concealed within the framework and operated by an internal flush handle. The shootbolt rods are manufactured in aluminium and linked by a corrosion resistant cam. They are capped with glass fibre reinforced polyamide cones to prevent any damage.

When closed each panel interlocks with its neighboring panels by the means of tongue and groove molded connecting blocks and continuous gasket seals. All systems are internally glazed as standard for improved security.

Key locking can be integrated in the first opening panel or lead door with a five-lever profile cylinder, this can be fitted to either the inside only or both internally and externally as required, additional locks can be added at every handle point for higher security

Weather stripping

The top and bottom seals consist of twin nylon brush piles giving an effective seal. The double gasket seals between the door panels are continuous and of superior quality (consisting of long lasting EPDM).

Operating System

A top running system with an operating mechanism that consists of double horizontal stainless steel polyamide coated wheels with maintenance free sealed ball bearings providing continued quiet, quick and easy, smooth operation and a long life.

Appearance

The natural character of wood is perfectly preserved by using Sikkens micro-porous water based wood stains (i.e. they contain no harmful solvents) in a variety of stain colours. Or alternatively the timber can be paint finished to any RAL colour (over 201 RAL colours available) or different colours or woodstain to the inside and outside. As standard Sunflex timber door systems are fully finished which consists of one basecoat and two topcoats; other finishes are available upon request.

Complete System

Designs can be customised according your preference - the options include mid-rails, mullions, plant-on bars with dummy spacer grids, deeper top and bottom profiles and solid in-fill panels, among many others.

Glazing

The system is internally glazed and can accommodate glazing ranging from 4mm clear toughened glass up to a sealed unit of 38mm. Our standard 28mm unit comprises of 4mm clear toughened glass with Low 'e' to the inner pane x 20mm argon gas cavity x 4mm clear toughened glass to comply with building regulations for safety and thermal efficiency. All units are BS kite marked, manufactured to BS6206A and BS5713 standards.

IDSystems offer a wide choice of glazing options, including manual or electrical internal venetian or pleated blinds which can be incorporated inside the glazed unit. These are very popular, especially on internally opening systems where curtains are not practical.

U-values and heat losses

A U-value is a calculation of the amount of heat lost through a building material. The calculation of U Values can be quite complex as it is measured as the amount of heat loss through a 1 square metre of material for every degree difference in temperature either side of the material. It is indicated in units of watts per square metre per degree Kelvin or W/m2K. The simplest way to approach u-values is the lower the u-value the more thermally efficient a product is.

A u-value of a door or window is calculated by working out by determining the u-value of the frame and the area of the glass and is then quoted as an overall u-value. Beware that some manufacturers may just be providing the u-value of the glass alone which gives a false overall value. All of our systems have been thermally simulated in accordance with CE standards to EN 10077.

Building Regulations approval will be required on all extensions and new builds to which we are able to provide CE data showing compliance. Any replacement works we are able to cover being a member of Fensa and a certificate would be provided on completion of our installation.

Triple glazing is becoming increasingly popular, especially in total new builds, as it provides the lowest u-values possible and can be up to 40% more efficient than double glazing. Combining two panes of low-e glass and two gas filled cavities glazing u-values as low as 0.5W/m2k are possible with the added benefit of great sound reduction.

Solar control and the benefits of solar gain

With the standard glass specification retaining as much heat as possible you may wish to consider reducing the heat transfer from outside which is known as solar gain. Solar gain can make glass roofs, conservatories or south facing elevations quite unbearable in the height of summer months like stepping into a greenhouse. A solar control glass is a glass with a either a special coating or a body tint to reduce the amount of heat entering a building either by reflecting or absorbing heat. Using a solar control glass can reduce the need for air conditioning and blinds. Whilst the solar control glasses are great at reducing the heat they will also have an impact on light transmittance.

Building control often recognise the benefits of solar gain in modern buildings as large areas of glass will work as a source of free energy during cooler months and increased solar gains are recommended The use of low-iron glass can increase the heat and light transmittance to provide further solar gains during the autumn and winter months. Many modern designs incorporate overhangs to glazing to cast shadows over glazing during the summer combatting the solar gains, thus allowing solar gains as the sun gets lower in the sky later in the year reduing the need for heating.

Safety glass

As standard we fit toughened glass to comply with Building Regulations Document N as an alternate method of compliance we are able to fit laminated glass. Both options have their pros and cons

Toughened glass

Toughened glass has been heat tempered to increasing its strength over ordinary annealed glass by up to five times. Other than the strength the advantage of toughened glass is that should it break it would shatter into non-sharp pieces. It is also available with the widest variety of coatings and can be supplied in larger sheets than equivalent thickness laminated glass. When the glass is toughened it can suffer from some visual distortion making, meaning the face of the glass isn’t perfectly flat distorting some reflections. Thicker toughened glasses are less susceptible to visual distortion; please contact us for further advice.

Laminated glass

Laminated glass is manufactured by bonding two panes of annealed glass with a clear plastic interlayer. The benefit of laminated glass is that if it’s broken the glass will crack rather than shattering, improving security. In addition, laminated glass reduces bleaching of carpets, curtains and furniture by filtering ultra-violet rays that would usually penetrate the glass. The drawback of laminated glass is that extreme heat or cold can cause invisible defects in the glass to form a crack due to the two panes expanding and contracting independently. As the laminated glass is not toughened is does not suffer from the visual distortion that can occur to toughened glass during the toughening process.

Custom designs

As well as offering full height clear glass we can also provide a more traditional style of glazing by incorporating glazing bars, Georgian grids or lead work. Please contact us for further information.

Cat flaps

Often neglected when planning your new build or extension is where a suitable space may be for your feline friend, we have the ideal solution. It is possible to have a cat flap fitted into a glazed panel by cutting a circular hole into the toughened glass unit for you to fit an in-glazed cat flap.

Venetian blinds

We are able to fit Venetian blinds withing the glazed unit, ensuring a totally dust-free environment which requires no cleaning or maintenance. These are very popular, especially on internally opening systems where curtains are not practical.

Integrated blinds can be tilted to help prevent the build-up of excessive heat and glare of the sun during the daytime and provide privacy when closed. Blind units can be manually operated with an ingenious magnetic control device or electronically operated via remote control. Please visit our dedicated blinds pages for further information.
